Some headaches do not come from the head. They come from the upper neck, and they are routinely treated as migraine or tension headache for years without anyone examining the neck at all.
The name for this is cervicogenic headache, which simply means "headache originating from the neck". It is thought to account for somewhere between 15 and 20 percent of chronic headaches, which makes it common enough to be worth ruling in or out.
Why a neck problem produces head pain
The nerves supplying the top three segments of your neck share a relay station in the brainstem with the trigeminal nerve, which supplies the face and much of the head.
Because these inputs converge on the same place, the brain cannot always tell which one is sending the signal. Irritation from an upper neck joint, disc or muscle gets interpreted as pain in the head, most often behind the eye, at the temple, or across the forehead.
This is the same mechanism that makes a heart attack hurt in the left arm. The pain is real and the location is genuine; the source is simply somewhere else.
How to tell it apart
Cervicogenic headache has a fairly distinctive signature:
- Always the same side. It rarely swaps sides, and rarely affects both at once
- Starts at the base of the skull and spreads forward over the head or behind the eye
- Provoked by neck movement or by holding an awkward neck position
- Reduced neck movement, particularly rotation, often noticeably worse on the painful side
- Steady ache rather than throbbing
- Tender to press at the base of the skull on the affected side
- Sometimes accompanied by a vague ache in the shoulder or arm on the same side
Compare that with the two conditions it gets confused with:
| Cervicogenic | Migraine | Tension type | |
|---|---|---|---|
| Side | Same side every time | Often one side, can swap | Both sides |
| Quality | Steady ache | Throbbing, pulsating | Pressing, band-like |
| Triggered by | Neck position and movement | Foods, sleep, hormones, light | Stress, fatigue |
| Nausea and light sensitivity | Uncommon or mild | Common and marked | Uncommon |
| Neck movement | Clearly restricted | Usually normal | Usually normal |
| Response to painkillers | Poor | Often good early | Often good |
That last row is what usually brings people in. When simple painkillers reliably do nothing, it is worth asking whether the problem is being treated in the right place.
The distinction is not always clean. Neck pain occurs in a majority of migraine attacks too, so a stiff neck alongside a headache does not by itself prove the neck is the source. What points to the neck is that neck movement and position provoke and relieve it.
What causes it
- Sustained desk and screen postures, loading the upper neck joints for hours
- A previous neck injury, including whiplash, sometimes years earlier
- Sleeping position, particularly on the front with the head rotated all night
- Degenerative change in the upper cervical joints
- Deep neck flexor weakness, leaving the small stabilising muscles unable to support the head, so larger muscles and joints take the load
The last one is why this so often coexists with ordinary desk related neck pain. Our guide to neck pain from desk work covers the postural side, and desk setup covers the environment.
What helps
Manual therapy to the upper neck. Mobilisation of the top three cervical segments has reasonable evidence for cervicogenic headache specifically, and often produces noticeable change within a few sessions. This is one of the conditions where hands on treatment earns its place rather than merely feeling good.
Deep neck flexor training. The chin tuck, done properly, is the cornerstone. Lying on your back, gently nod as though saying yes to a small question, hold ten seconds, repeat ten times. It should feel like almost nothing. If the front of your neck is straining, you are using the wrong muscles.
Upper back mobility. A stiff thoracic spine forces the neck to compensate. Seated rotations and extensions over a chair back, daily.
Fix the sustained positions. Screen at eye level, phone raised rather than head lowered, and a change of position every half hour. Ten seconds of movement every thirty minutes beats ten minutes of stretching once a day.
Review your pillow. One pillow that fills the gap between your head and the mattress, keeping the neck level. Front sleeping is the position to move away from, because it holds the neck rotated for hours.
A realistic timeline
If the neck is genuinely the source, most people notice a change within three to four sessions and meaningful improvement within six to eight weeks alongside the exercises. If there has been no change at all after six sessions of neck focused treatment, the diagnosis deserves revisiting rather than persisting.
See a doctor urgently if
A headache comes on suddenly and severely, is the worst you have ever had, follows a head injury, comes with fever and a stiff neck, comes with visual loss, confusion, weakness or slurred speech, is worse lying down or on coughing, or begins for the first time after the age of 50.
Those features are not physiotherapy problems and need medical assessment the same day.
Otherwise, if your headache has been on the same side for years, starts at the base of your skull and shrugs off every painkiller you have tried, an examination of the neck is a reasonable next step, and often an overdue one.
